Glock newbie - "pocket" carry

123

It's my wife's pistol, but I am planning on carrying it on a motorcycle trip we are taking soon. My Walther PPS doesn't have the capacity and my CZ 75B and 1911 or just too bulky and heavy for this particular application.
I was planning on packing it in my front zippered pocket of my motorcycle jacket (two large, zippered pockets on the front of the jacket (left and right) and realized that might not be a wise thing. I don't even pocket carry my Beretta Tomcat without a holster and its a double-action, heavy trigger pistol (.32 cal).
Are there "pocket holsters" for this large of a pistol or am I just being a little paranoid.

Yep have a carry permit. Have a tactical style shoulder holster but have not worked with it yet. Had not seen the option from glocktech before. But a little late to get one orderer to try it out. But probably will just to see how it does.
But with the big pocket capable of holding a glock 19, that still seems unsafe. Essentially think of it as something like throwing it into a fanny pack.
Would you throw a glock into a fanny pack?
